Cell homing at the wound site (A) Tracking of hUC-MSCs was performed at day 14. DiI labeled red fluorescent cells representing hUC-MSCs were observed around the center of wound lesion. Some labeled cells are indicated with white arrows (B) Quantitative analysis of labeled cells represent significant increase in the fluorescence intensity in the treated groups as compared to untreated control. Statistical analysis was performed using one-way ANOVA with Bonferroni post-hoc test. Data is represented as mean ± S.E.M (n = 3); p-value ≤ 0.05 was considered statistically significant (where ∗∗∗ = p < 0.001, ∗ = p < 0.05).
